Intensification of livestock production

With population and income growth, demand
for animal products has risen rapidly over the last 20
years. With the intensification of livestock production,
global production of meat and eggs have risen by 127 percent
and 331 percent respectively. This compares with a 78
percent increase in cereal production. But the risks of
intensification - in the shape of animal disease epidemics
and environmental degradation - can no longer be
ignored.
